This button is adapted to beturned so that it will engage over the top edge of the jaw-plate 13, as shown, thereby holding said plate place.

Acoiled resistance-sprihg 37 isatatched at one'end by means of an ear 38 to the base 20 of-the movable jaw, and its other end issecured to the bar 12 of the boxing, as shown.

In use the stationary jaw-plate'13 is secured rial to be crushed is dropped between the up:

per ends of the jaws. Upon rotating the shaft it will be evident that the movable jaw will be oscillatedback and forth towardand from the stationary jaw, and as the material is broken it will gradually descend toward the lower ends of the jaws untilit has been crushed fine enough to pass between said lower ends.

Should it be desired to vary the grade, it will be evident that by rotating the screw in one direction or the other the lower end of the movable jaw will be -moved toward or from the stationary jaw, thus varying the size of the opening between said jaws.

The particular'arrangement of the link and crosshead, as shown, prevents any tendency of one side of the movable jaw being spacedfarther from the stationary jaw than the other side, and thus the grade, whether fine or coarse, will always be uniform. The spring ,employed holds the movable jaw, .the link, and the cross-head in their coacting relations, but

permits the ready disassociation of these members should it be necessary to-replace or rebeen passed through the machine'and it is de- 3. A linkfmay be readily and tho'roiighly cleansed by simply turning the button 17 and removing? the jaw 13. This jaw may then be thoroughly brushed to remove all adhering'particles, and the space within the box-ing will be suflicient to give; complete access to the operative face of the movable jaw. As'a result itjwill be seen that the objects mentioned in. the preliminary portion of the specification are accomplished, and, further than this, the structure is comparatively simple, and the parts are so arranged that there is little chance of derangement or injury. These parts, however, are inexpensive to construct,and any or all may be removed-when worn and replaced by others.

From the foregoing it is thought that the construction, operation, and many advantages ofthe herein-described invention will be aper descr'iptionfandit will be understood that various changes in the size, shape, pro

'In a crusher of the class described, the combination with a supporting-frame having" oppositely-disposed seats, of a jaw-plate having a handle on its upper end, and provided with po'rtionson its opposite side edges that detachably engage in the seats, and a turnbutton mounted upon the frame betweenthe seats and engaging over the top of the jaw- .plate within the handle to hold said plate in place in said seats. a

In a crusher of. the .class' described, the combination with a frame comprising a box-1 ing having seats in the upper'portions of its opposing innerjsides, said seats tapering to their lower ends and toward the inner, faces of said sides, of a jaw-plate having tapering lugs that project from its sideedges and detachably fit in the seats, said lugs conforming -.to the shape of said seats, and a turn-button rotatably mounted on the upper end of the boxing between theseats and movable over- .the upper edge of the jaw-plate.
